Case file
IP-based nurse call systems with bedside, bathroom, code-blue and staff-presence stations, integrated with mobile and PA.
/ The discipline, in detail
How we approach nurse calling system.
A modern nurse-call system measures itself in response time, not just call origination. Bedside calls escalate to mobile devices on configurable timers. Staff-presence buttons cancel calls only when the nurse is in the room. Code-blue triggers light up at the nursing station, the corridor dome, the duty pager and the cellphone simultaneously. Every event — call, accept, cancel, transfer — is logged for service-quality analytics.
On record
Every nurse calling system engagement is documented end-to-end — design, programming, commissioning, calibration — and handed over with the files our successors would need if we were never to return.
/ Where we deploy this
Active across 1 sector.
Nurse Calling System is rarely a standalone brief — it sits inside a wider sector practice with its own codes, expectations and operating rhythm.

CCTV design for hospitals: privacy zoning, retention windows and the camera count nobody calculates
Hospital surveillance is not a commercial brief with a medical sticker. Patient privacy, infection-control zoning, NABH audit retention and clinical-engineering veto rights mean the camera plan, the storage sizing and the analytics rules all read differently. The design discipline we have built around it.

BMS retrofit playbook for occupied hospitals
A BMS retrofit in an occupied hospital is unlike any other commercial BMS retrofit. Patient-care continuity, NABH compliance, infection-control zoning and theatre uptime turn what would be a 12-week commercial project into a 28-week clinical exercise. The playbook we have learned across multiple projects, including the Tinsukia Medical College & Hospital delivery for NCC Limited.

/ Frequently asked
Nurse Calling System — what buyers ask first.
What is HTM 08-03 and do we need it?
HTM 08-03 is the UK NHS nurse-call standard, widely adopted as international best practice — defines call categories, escalation timers, audibility and reliability. The UK NHS nurse-call standard, widely adopted as international best practice. It defines call categories, escalation timers, audibility and reliability. We design to HTM 08-03 even for private hospitals because it produces a measurably better patient experience.
What does a NABH-readable nurse-call system include?
Bedside call station, bathroom emergency pull, patient-station handset with voice, staff-presence button, code-blue emergency, dome-light corridor indication with priority colour code, central nursing-station console with audio and patient identification, integration with patient-monitoring and call-routing logic. We engineer to NABH and JCI accreditation expectations.
Which nurse-call platform is right for a hospital?
Choice follows the hospital's workflow, bed-system integration, nurse-mobility needs and reporting requirements. Premium hospitals usually need occupancy and exit-alert integration, workflow analytics, DECT or smartphone routing, and a service model the biomedical and nursing teams can operate confidently.
How is a code-blue actually handled?
A red code-blue button at any bedside or bathroom triggers immediate audio-visual alarm at the central console, automatic dispatch to the response team's mobile or pager network, dome-light at the room corridor, and integration with the building PA for overhead announcement if configured. The cause-and-effect logic is programmed once and tested per shift.
Wired or wireless nurse-call?
Wired is the right answer for any new hospital — reliability above 99.9% is required and wireless cannot match it. We retrofit wireless extensions only where adding a station to an existing wired backbone is more disruptive than the wireless reliability cost.
What's the AMC for a nurse-call system?
Quarterly preventive checks across all bedside, bathroom and corridor equipment (button function, dome lights, audio paths), annual full-system commissioning re-test, response-time SLA written for code-blue events. Spare console, dome lights and beside stations held in our office. AMC runs 10–14% of installed value annually given the criticality.
